Even if you watched The Hobbit trailer at 1080p off of Apple's site the fidelity of the data is nowhere near the quality of what would have been seen in the theater at CinemCon.

4K is actually 4x the resolution of 2K. 2K is what we are used to in theaters. 1080p is closed to 2K in resolution and is what we are used to for HDTVs. However, the trailer file is SUPER compressed...

The 24fps we have seen would not be as bright or as fluid as the 48fps (by virtue of the fact that you are seeing twice the amount of frames in a second than before) but as I have maintained all along... web compression is where the quality is suffering as well.

I saw The Hobbit trailer in 3D 4K before TinTin at 24fps and it looked INCREDIBLE!

The trailer is definitely in a more finished state than what they saw at CinemaCon.

In fact, when I read the summary of Quickbeam's report... What they saw is nowhere near finished.

So resolution matters, fps matters, compression, the stage at which people are seeing the content. It's actually very brave for PJ to be this transparent. Middle Earth is New Zealand!
